When multiplying by 10 how many spaces do you move the decimal point

Mathematics
1 answer:
shusha [124]3 years ago
3 0

Answer:

If you multiply a decimal by 10, the decimal point will move one place to the right. If you divide a decimal by 10, the decimal point will move one place to the left.

Step-by-step explanation:

Multiplying a decimal by 10 increases the value of each digit by 10. Multiplying a decimal by a power of 10 increases the value of each digit by a number of times that is equivalent to that power of 10. When a digit's value is changed, that digit is moved to the appropriate place.

In the figure BE||CD solve for x. Show work
nataly862011 [7]

Answer:

The value of x = 15.

Step-by-step explanation:

Given:

BE || CD

AE = 9

ED = 6

AB = x

BC = 10

To Find;

AB = x = ?

Solution:

BE || CD ......................{Given}

Basic Proportionality Theorem:

If a line is parallel to a side of a triangle which intersects the other sides into two distinct points, then the line divides those sides in proportion.

i.e

\frac{AE}{ED} =\frac{AB}{BC}...........{Basic Proportionality Theorem}

Substituting the given values we get

\frac{9}{6} =\frac{x}{10}\\\therefore x = 10\times \frac{9}{6}\\\therefore x = \frac{90}{6}\\\therefore x = 15

The value of x = 15.
